Handler, activeWhen, PropertyTester and multiple selections [message #326332]

Hi everyone!

I'm using a handler for a command that should be active when the
internal state of the selected item is 'unlocked'. 'unlocked' is a user
defined value and checked with a PropertyTester class.

My problem: when I selected multiple items and one of them has the state
'locked' the handler is not active. I understand: an and condition :-)
but can I change this to an or condition?

Thanks for reading and solutions!

Timo

....
<activeWhen>
<with variable="selection">
<iterate operator="or">
<test property="...your property..." value="unlocked"/>
</iterate>
</with>
</activeWhen>
....

should do.
